Snubline vs Interview

Explore rigging physics with an educational model. Snubline uses assumed inputs to illustrate equations and compare numerical values. It has no independent professional validation or complete rope calibration dataset. It is not a professional planning or load-safety assessment tool. Do not use its results to select equipment, determine actual loads, plan a cut, or decide whether an operation may proceed. Obtain qualified on-site assessment independently of the app. THE EDUCATIONAL MODEL - Compare snubbed and constant-slip let-run assumptions using a closed-form spring-mass equation. - Inspect peak tension, dynamic load factor, stretch, block force and device force, with equation details. - The rope conversion factor 0.075 and example moduli are provisional teaching values. - The 75%-125% display range is illustrative, not a validated error bound or confidence interval. Actual loads may fall outside it. - Fall factors above 2 are limited to 2, with a visible warning; the result no longer represents the full entered drop. NUMERICAL FORCE-VERSUS-RATING COMPARISONS Enter your own tag ratings and design factors. Within WLL, Approaching WLL, Exceeds WLL and Exceeds MBS describe numerical comparisons of model values only. They do not approve equipment or operations. EXAMPLES AND DOCUMENTS Estimate log weights from idealized geometry and species density, with estimate labels carried into comparisons. Save scenarios, gear records and jobs. Compare scenarios and share educational comparison PDFs or images. Existing frozen snapshots remain stored; documents rendered by this version carry the current educational restriction. TRANSPARENCY The free model page explains equations, provisional calibration, formula-test limitations and omitted effects including swing, tree flex, rope heating, friction variation and fatigue. Climbing, life support and crane operations are outside the model. YOUR DATA Records remain on your device. No account or cloud sync. If saved records cannot be opened, recording is paused and existing database and attachment files are kept. FREE Both model modes, equation details, the weight estimator, the model page, three Gear Locker items and one job. PRO Unlimited Gear Locker items and jobs, what-if comparisons, PDFs and share cards, custom rope profiles and widgets. Pro does not change model validity or calculation correctness.

Record the conversation. Get a transcript that says who said what. Nothing ever leaves your phone. Interview is a recorder for conversations that can't leak: client meetings, interviews, research sessions, anything you'd rather keep to yourself. Tap Record, talk, tap Done. Minutes later you have a transcript with every line labeled by the person who said it. All of it happens on your phone. No account, no servers, no upload. The only way an interview leaves your phone is when you share it yourself. KNOWS WHO'S TALKING Interview tells the voices in the room apart and labels every line. Name a speaker once and everything they said is labeled. If it isn't sure, it asks instead of guessing. REMEMBERS THE PEOPLE YOU INTERVIEW Name someone once and Interview recognizes them next time. It learns your own voice during setup, so you're labeled automatically. Remembered voices are yours to delete, any time. SHARE ON YOUR TERMS Send the transcript as text, Markdown, Word or PDF, with or without the audio. Nothing is shared until you choose to. SPEAKS YOUR LANGUAGE Transcribes 33 languages and picks the right one on its own: Arabic, Cantonese, Catalan, Croatian, Czech, Danish, Dutch, English, Finnish, French, German, Greek, Hebrew, Hindi, Hungarian, Indonesian, Italian, Japanese, Korean, Malay, Mandarin, Norwegian, Polish, Portuguese, Romanian, Russian, Slovak, Spanish, Swedish, Thai, Turkish, Ukrainian and Vietnamese. Some languages need a one-time download from Apple the first time. Titles and summaries come from Apple Intelligence, which writes them in Danish, Dutch, English, French, German, Italian, Japanese, Korean, Mandarin, Norwegian, Portuguese, Spanish, Swedish, Turkish and Vietnamese. Recordings in other languages still get the full transcript, dated instead of titled. ALREADY HAVE A RECORDING? Import audio or video, or paste a link to an episode or audio file, and get the same transcript. PRIVATE BY DESIGN • No account, no sign-in • No servers, no upload • Delete means gone Made for anyone who cares about privacy. Lawyers, journalists and researchers use it, and so can anyone who'd rather keep a conversation their own. Works best on iPhone 12 or later. Titles and summaries need Apple Intelligence.
